Peter Jackson is preparing to adapt another bestseller to the screen, this one without any hobbits or elves. Variety reports that the ''Lord of the Rings'' director will take on Alice Sebold's 2002 novel ''The Lovely Bones'' after he finishes his current project, the remake of ''King Kong.'' Jackson and his fellow ''Rings'' screenwriters Fran Walsh and Philippa Boyens will adapt the story of a 14-year-old girl who, after being raped and murdered, looks down from heaven as her family copes and the killer continues to elude the police. Scottish director Lynne Ramsay (''Morvern Callar,'' ''Ratcatcher'') had previously been attached to direct and cowrite the movie. It's not clear how the film passed into Jackson's hands. Nor is it clear when the Jackson team will make the film (their work on ''Kong'' will keep them busy through 2005) or which studio will buy the distribution rights. Of course, with Jackson attached, a story about a raped and murdered girl and a devastated family suddenly doesn't sound like such a tough sell.
